Answer:

Point (2,0) Is Not a solution. The solution to this system is (0,2). The point (2,0) is not in contact with any line. Since (x,y) Is how the formula is, and the solution is on the y line not the x.

Yo sup??

We can verify this just by pluggin in the value (2,0) into the function

g(x)=3x+2

when x=2

g(x)=3*2+2=8≠0

Therefore (2,0) is not a solution of g(x)

Similarly

f(x)=|x-1|+1

=|2-1|+1

=2≠0

Therefore (2,0) is not the solution of f(x)

Since (2,0) doesn't satisy the 2 equations therefore its not a solution of the system of equations.

Other method would be to see whether the lines pass through (2,0)

Hope this helps.

A candy company claims that its jelly bean mix contains 15% blue jelly beans. Suppose that the candies are packaged at random in
I am Lyosha [343]

Answer:

Doubtful.

Step-by-step explanation:

Our values are,

P=0.15 \rightarrow 15\%Jelly Bean Mix.

The sample for us is n=200

And our proportion (x) is 40 .

We can calculate  with this dates the sample proportion and make he test statistic.

p=\frac{x}{n} = \frac{40}{200} = 0.20

H_0:P=0.15

H_1:P \neq 0.15

We use the formula for Test statistic, that is given by,

z= \frac{p-P}{\sqrt{\frac{P-(1-P)}{n}}}

z= \frac{0.20-0.15}{\sqrt{\frac{0.15(1-0.15)}{200}}}

z= 1.98

We see that our P-value: 0.048 (From the Table)

We note that p-value is less than 0.05, so we should to rejecyt the null hypothesis and conclude that the calim is doubtful

Cole has 5 times as many pencils as
Nataly [62]

Answer:

Cole has 15 pencils.

Step-by-step explanation:

First, we have the equation c + o =18, c representing cole, and o representing connor.

From there, we get 5o=c

Using substitiution, we get o=3

5(3)=15

15+3=18

Complete the steps 4/9 divided by 1/2
DedPeter [7]

Answer: 0.88 (the 8 recurs)

Step-by-step explanation:

\frac{4}{9}÷\frac{1}{2}

\frac{4}{9}×\frac{2}{1}  (Then the the fraction should reciprocal so the values should shift to          the opposite side were 2 goes up and 1 goes down and the sign turns to the multiplication sign)

then u should multiply the two fractions which gives 8/9

next you should divide 8 by 9 which gives 0.88(the number eight is recurring which means that the number 8 keeps repeating no matter how many times you try to divide)
